IPC: G06F3/046
Filed: 1992-10-09
Abstract: PURPOSE:To easily detect operation information even when a switch is operated in any timing by comparing the sum of induced voltage measured last time and this time on a prescribed condition, and executing the detection processing of a switch operation based on the compared result. CONSTITUTION:When a switch SW1 of a position instructor 2 is operated, capacitors C0 and C1 are connected in parallel, and a tuning circuit is formed of the capacitors C0 and C1, and a coil L. Therefore, at the time of detecting the operation information of the switch SW1, a processing circuit 17 supplies the driving currents of the same frequency as the tuning frequency of the tuning circuit formed of the capacitor C0 and the coil L to a driving coil group 11 so that the maximum induced voltage from a sense coil 14 side can be obtained. When any switch is operated, the frequency of the driving currents is not matched with the tuning frequency, and the detected voltage value is decreased, even when the position instructor 2 is not moved. Therefore, the operation of the switch can be detected by detecting the decrease of the voltage.

Title: Buried type semiconductor laser
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/00
Filed: 1985-12-27
Abstract: PURPOSE:To make it possible to form, with excellent yield, a semiconductor laser which is free from optical damage, of large output, of low threshold value and of high efficiency, by making an active layer absorbing oscillation light not present in the vicinity of a reflection end surface, and introducing a layer of low Al composition at the time of buried growth in a window region. CONSTITUTION:An n-type clad layer 2, n-type light waveguide layer 3, active layer 4, p-type intermediate layers 5 and 6, p-type clad layer 7 and p-type electrode layer 8 are formed in order on an n-type sbstrate 1 by epitaxial growth. Mesa etching is performed in the form of an inverse mesa leaving a light emitting part only, and the width of a window region is made narrower than the light emitting part. An intermediate layer 5 and the active layer in the window region, and the active layer in a construction part 14 are eliminated by etching, and an n-type buried layer 9 and a p-type buried layer 10 are formed. Thus, an n-p inverse bias junction is formed in the vicinity of a p-n forward direction bias junction in the light emitting part, and current constriction is enabled. In the window region, the light waveguide layer 3 is surrounded by the layers of low refraction index, 9 and 10, and the n-type clad layer 2, and so acts as an excellent light waveguide mechanism. At the time of forming the layer 10, the p-type layer 6 of low Al composition is exposed, and then it is easy to bury the layer 10 by making the super-saturation degree of a solution high, because an oxidation scarcely ever occurs.

Abstract: PROBLEM TO BE SOLVED: To prevent contamination of a starting material at the time of production of an amorphous powder and to enable arbitrary regulation of rapid cooling conditions and flat state by a relatively simple apparatus. SOLUTION: A large amount of impulse current is applied to a wire shaped metallic starting material disposed in an atmosphere of a cooling medium of nonoxidizing gas, such as gaseous nitrogen, argon, and hydrogen, to form a molten part, and the molten part is scattered, in a state of high-speed fine grains, in the atmosphere by the wire explosion occurring in the inner part of the starting material by the application of the large amount of impulse current and the high-speed fine grains are allowed to collide against a cooling body 41. The starting material is strung between electrodes 23 and can keep its purity without causing contamination by a melting atmosphere as in the case of melting in a state of contact with a contamination source such as a crucible.  Moreover, this starting material is scattered, in a state of high-speed fine grains, in the cooling atmosphere by the wire explosion and further allowed to collide with the surface of a cooling body, by which cooling conditions for making amorphous can bee easily obtained.
